World Cup knockout “To Advance” badges on FanDuel, DraftKings, and Kalshi — compare 2-way knockout prices separately from 90-minute match odds.
Live in-play comparison on FanDuel, bet365, Sky Bet, Betfred, and Virgin Bet / LiveScore Bet live pages.
World Cup outright badges on Smarkets, Kalshi, and Novig tournament Winner markets (where we have feed coverage).
Clearer prop overlays — Best Price and Compare All modals show Yes/No and Over/Under pills; goalscorer labels no longer repeat the player name.
Outright & soccer fixes — tournament Winner prices no longer bleed onto sibling markets (group winners, Golden Boot, etc.); restored badges on Caesars MLB World Series outrights, LeoVegas outrights, BetMGM World Cup 3-way lines, and Kalshi draw (Tie) buttons.
Faster, more reliable loading — knockout/prop odds load with the main fetch; fewer duplicate API calls; smoother DraftKings World Cup tab navigation; Kalshi regular match rows detect correctly again.

New

Live in-play overlays on DraftKings (/live) and Novig (/trading/live) — comparison badges on multi-sport live lobbies across spread, total, and moneyline markets.
Smarter sportsbook launch links — the bookmaker directory opens overlay-rich league/lobby pages when configured, instead of always landing on the homepage.
Fixes

bet365 — World Cup hub on mobile, mobile MLB/NFL game lines, homepage coupon grid (#/HO/), and lazy-loaded lobby discovery.
888sport — live betting lobby and match list overlays.
Caesars — World Cup soccer matches (no longer misread as American football).
William Hill — correct Home/Draw/Away badge placement on 3-way match feeds.
Compare All — long bonus text wraps instead of pushing odds off-screen.
Overlay header — event title keeps its themed color on sites that override styles.
BC.GAME — click tracking resolves the display name to the correct bookmaker for affiliate attribution.

What's New in 1.0.1.19

• Compare overlays now show active bonus title and headline offer under each sportsbook in the price-comparison modal and Compare All table.
• World Cup comparison badges added for ProphetX, Novig, and bet365 (matches and outrights).
• William Hill World Cup badges restored after platform update.
• Coral & Ladbrokes: fixed badge alignment on 3-way match grids.
• Improved install attribution when you install from an OddsGuard landing page.
• OG Labs: Location Mode now requires the location_mode invite entitlement.

Added
Invite code celebration — redeeming a theme or feature invite in Settings → Overlay style shows a confetti modal listing what unlocked.
BetUS supported — comparison badges on BetUS game pages (MLB, NFL, NBA, NHL, college, FIFA, major soccer) and outright/futures pages.
Marketing attribution — website bridge syncs session UTMs into extension storage for install tracking.
Changed
Invite code celebration modal — solid card background, clearer section labels (Extension Themes / Invite Only Features), confetti above copy at 2× duration.
Fixed
BetRivers MLB World Series — badges on every World Series Winner futures candidate.
BetOnline + LowVig MLB World Series — badges on all outright rows, including per-candidate Yes/No contests.
BetRivers MLB — badges on matchups with starting pitchers listed (pitcher stat line excluded from team-name parsing).
VegasInsider price capture — spread/total cells use American odds, not line values; "even" resolves to +100.
Team name matching — DOM labels use the same cleanup as polling (doubleheaders, golf round noise, bet365 prefixes).
Best-price thumb-up — suppressed when there’s nothing to compare against.
Everygame MLB-Lines — badges for ARI, CHW, SDG, SFO, TAM; pitcher names stripped from team codes.
Novig — expanded lobby, event-detail, and autofill outright coverage.
Outright markets — better overlay positioning on multi-column tables (Top 5/10/20).
Bookmakers directory — clicks use extension-native track-click with installation ID.
VegasInsider — badges re-render on tab/period switches; futures pages show per-runner badges on every column.
OddsShark futures — badges on every bookmaker column per runner.
Golf matchups — bet365 round-noise labels match API team names.

WHAT'S NEW IN THIS VERSION

Calculators
• New Calculators tab in the iOS app with fifteen betting tools — parlay, arbitrage, Kelly criterion, hold/vig, odds conversion, round robin, and more — matching the website calculator suite.

Safari Extension — Overlays & Comparison
• Oddschecker: comparison overlays now reflect OddsGuard's best price across all supported books and regions, not only the UK aggregate Oddschecker displays.
• Oddschecker match pages (tennis singles, football fixtures, Compare-All layouts) now show comparison badges on individual event pages.
• New Stake.com sportsbook support on sports, live, league, and futures pages.
• Outright/futures overlays expanded on Bet365, Betsson, BetOnline/LowVig, Betway, BetVictor, and BetParx pages that previously showed no badges.
• FanDuel sport hub tabs (Live Now, Upcoming, league views) resolve to the correct sport when the page URL drops query parameters.
• Compare All and best-price badges now rank only books on the same point spread or total line as your selection.
• Spread and total quotes with unrealistic modelled value are filtered from rankings unless freshly updated.

Safari Extension — UI Reliability
• Floating action button menus and bonus panels are isolated from aggressive sportsbook CSS so icons, fonts, and card layouts render correctly on sites like BetVictor, BetUS, and 1xBet.
• Modal dialogs opened from the bonus panel (Compare All, forms, detail views) are similarly protected from host-page style overrides.
• Compare All and Parlay Compare modals scroll properly on mobile Safari; parlay disclosure can be collapsed to see more pricing rows.

Location & Compliance
• Geolocation requests allow more time on slow networks before timing out, with faster automatic retry after transient failures.
• Location cookie refreshes when your network IP changes (travel), reducing stale region detection.
• Parlay calculator age badge (18+/21+) uses the same cached location as the floating action button for faster, jurisdiction-correct display.
• Safari iOS privacy consent now shows separate, explicit copy for the host app versus the Safari extension — accepting in one surface does not imply consent in the other.

Other Improvements
• Sport and lobby detection improved on URLs with ad/tracking parameters and hash-routed sportsbook pages.
• Alt+Shift+O keyboard shortcut now toggles overlay visibility on desktop browsers.
• iOS onboarding and Activate-tab improvements from prior release continue to refine first-run setup and extension enablement guidance.

Version 1.0.1.13 — User-facing update summary

This update adds 1xBet support, improves sport-category detection, adds a new support shortcut, and fixes several display and tracking issues.

What’s new

Added support for 1xBet on supported 1xBet sites.
OddsGuard can now show comparison overlays on supported pre-match, live, and outright market pages where odds data is available.
Added a new Chat quick action in the popup, giving users a faster way to contact support when chat is enabled.

Improvements and fixes

Fixed an issue where submenu icons could disappear on some sportsbook pages.
Improved detection for broad sport categories like basketball, baseball, ice hockey, American football, and MMA, so category pages are no longer treated as only NBA, MLB, NHL, NFL, or UFC pages.
Improved MMA page detection across multiple supported sportsbooks.
Improved affiliate routing reliability for supported partner links.
Fixed an attribution issue affecting Everygame links.

Notes

1xBet overlay coverage depends on available odds data by sport. Soccer, baseball, and basketball are currently supported; additional sports coverage is still being expanded.

OddsGuard Firefox Extension – Release Notes

Summary of changes since last Firefox build (~1 month ago)
Current Firefox manifest version: 1.0.0.3

Security and AMO warnings

• Unsafe assignment to innerHTML:
  All dynamic HTML in the extension is now set via a single helper that sanitizes with DOMPurify before assigning to innerHTML. Overlay, badge, modal, and notification code paths use this helper so AMO’s “adequately sanitized” requirement is met.
  See FIREFOX-STORE-WARNINGS.md.
• Function constructor / eval:
  Documented that the warning comes from a bundled dependency (e.g. webpack runtime), not from application code; submission notes and mitigation options are in the same doc.

Cross-browser and compatibility

• Cross-browser support: Extension build and behaviour aligned for Chrome, Firefox, and Safari (MV3 where applicable, webextension-polyfill for Firefox/Safari).
• TypeScript and API usage: Improved type safety and cross-browser API usage in extension code.

Terminology and store compliance

• Responsible gaming: Added responsible gaming icons and related UI/links where appropriate.

New and updated bookmaker / provider support

• New adapters / regions: BetVictor, Unibet (multi-region), Grosvenor, BetMGM UK (Kambi), LeoVegas, William Hill, LiveScoreBet, BoyleSports, Coral, SkyBet, Ladbrokes.
• Fixes and improvements:
  Bet365 (3-way market detection, columnar layout handling), 888sport outrights, Betway outright overlays, LiveScoreBet 3-way and draw button placement, Plan D provider normalization, US Exchange region mapping, Kambi adapters and category bypass.

Overlay and modal behaviour

• Overlay clearing: Fixed overlay clearing bugs and consolidated container discovery and clear logic.
• Z-index: Overlay z-index and hover behaviour corrected so overlays stack and interact correctly.
• Event type and detection: Improvements to event type detection and overlay behaviour for different markets (e.g. outrights, 3-way).
• Modals: Compare All, Best Prices, and Detailed Comparison modals now share a single implementation in the modal-manager; duplicate logic and dead code in the overlay service have been removed.
